Wasting food makes me sad, but using plastic wrap and plastic bags for food storage makes me even sadder. Someone recommended that I try Stashers -- silicone food storage bags that are dishwasher & microwave safe, and totally reusable. I'm using way less plastic ever since. They don't take us much storage space, they clean easily in the dishwasher, and they have a range of sizes so you can store even small amounts of food. The food stays fresh longer, too, as far as I can tell -- bonus.
We have a bunch of these. They are the best ziplock bag replacements we could find. The way the close is superior to other options we've found. The ones we purchased a few years ago are still going strong. They've more than made up for the cost of buying sandwich bags and kept a lot of plastic out of our trash. Food can get stuck in the corners; I like to wash them inside out in the dishwasher (but Stashers says not to do that). It hasn't caused a problem with ours yet.
These are AMAZING! They are easy to use and even easier to clean, dishwasher safe! I have over a dozen different sizes and colors. They are very durable for all ages, especially small children AND they help save the planet! You can't beat that.
